8 mos old and baby is acting different LEAP?!?

Britt

Omg, my son turned 8 mos yesterday but something is going on with him. He’s always been a chill content happy smiley baby. The past 2 days he just SCREAMS, like you can’t do anything to make him happy. Will barely take a bottle while I’m away at work. I took him to the ped Monday and he checked out fine. I noticed he is in a LEAP and teething, but still is this normal ?
